Aerobic oxidation of primary aliphatic alcohols over bismuth oxide supported platinum catalysts in water

, 2013
Catalytic oxidation of non-activated aliphatic alcohols with molecular oxygen is rather challenging, especially in an aqueous medium in the absence of an additional base. Bismuth is usually used as a promoter of platinum-based catalysts.

O‐GlcNAcylated TAP1 Impairs Antigen Presentation and Promotes Immune Evasion in Bladder Cancer

Advanced Science, EarlyView.
This article unveils a critical mechanism of immune evasion in bladder cancer, which the O‐GlcNAc modification of TAP1 disrupts antigen presentation. This modification triggers HLA‐A degradation, shielding tumor cells from CD8+ T cell attack. The findings highlight targeting this pathway as a promising therapeutic avenue to sensitize tumors to ...

Biodegradation of plastic wastes under semi-aerobic condition with active methane oxidation activities and nutrient supply

Case Studies in Chemical and Environmental Engineering
Elimination of plastic waste deposition in landfills is essential to avoid secondary pollution such as microplastics. Under appropriate environments, methanotrophs which proceed through methane oxidation reaction are capable of degrading plastics via ...

Bacterial reduction of ferric iron and co-respiration of O2 and Fe3+ at various oxygen concentrations [PDF]

Acta Montanistica Slovaca, 2005
Acidiphilium SJH, was cultivated in laboratory bioreactor under aerobic, micro-aerobic and anaerobic conditions. The bacterium oxidized organic substratum D-galactose to carbon dioxide using oxygen and ferric iron as terminal electron acceptor.

Variability in aerobic methane oxidation over the past 1.2 Myrs recorded in microbial biomarker signatures from Congo fan sediments [PDF]

, 2014
Methane (CH4) is a strong greenhouse gas known to have perturbed global climate in the past, especially when released in large quantities over short time periods from continental or marine sources.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Chiral tetranuclear and dinuclear copper(II) complexes for TEMPO-mediated aerobic oxidation of alcohols : are four metal centres better than two? [PDF]

, 2014
The one-pot reaction of 3,5-di-tert-butyl-2-hydroxybenzaldehyde, (R)-2-aminoglycinol and Cu(OAc)2·2H2O in a 1 : 1 : 1 ratio in the presence of triethylamine led to the isolation of X-ray quality crystals of the chiral complex (R)-1 in high yield.
